Answer:
Step-by-step explanation:
The base of a cone is simply a circle.
The formula for the area of a circle is A = πr^2.
Example: What is the area of the base of a cone, if the radius of the base is 5 cm?
Answer: A = π(5 cm)^2 = 25π cm^2
Answer:
It takes 3 seconds for the diver to reach the water.
Step-by-step explanation:
The height, in feet, is given by the following equation:
How many seconds will it take for the diver to reach the water?
He reaches the water when his height is 0, that is, when h(t) = 0. So
There are no negative instant of time, so just t = 3.
It takes 3 seconds for the diver to reach the water.
Answer:
y=(3/2)x + 1
Step-by-step explanation:
use formula y=mx+b
M is slope
B is y intercept
use point (2,4) for Y2 and X2, and point (0,1) for Y1 and X2 to find the slope.
(Y2(4) - Y1(1))/ (X2(2) - X1(0)) =
(4-1)/(2-0)= 3/2 for slope=M
y intercept is just the point found on the y axis (0,1) so it's just 1. B=1
so then plug in the numbers for the variables.
y=(3/2)x + 1
